Hi,
The DC current of class AB Power Amplifier is according to the power level, as power increases, the DC current increases also.
But for different PA, the slope of the DC current increase is not the same. E.g. when 2 different transistor is biased by the quiscent current of 100mA, they have different DC current at 20dBm, 30dBm.
Does anyone know, which parameter determines this characteristics? Do I have any possibility to tune it?
Thanks in advance!
